Well today I found out that what I bought 18 years ago in boxes, bags and tin coffee cans does not contain all the necessary nuts and bolts for my old 52 1/2 ton Chevy. The engine has been rebuilt with new valves, rings and pistons bored .020 over, new bearings, fuel and oil pumps, gasket set and all the starting tools. What I don't have or can't seem to find are the bolts for the water pump, bell housing,thermostat housing and tranny. Does anyone have a master list of the correct sizes needed for all of the above mentioned mounting bolts and any other bracket, clip or spring to my old girl?
